This'invention relates to the Fourdrinier end of a paper making machinewherein the usual heavy metal frame supporting the table rails, tablerolls, deckle mechanisms and the breast roll is omitted thereb providingwhich may be termed a frame ess type of Fourdrinier section havingresilient wooden spring members on which the table rails and the breastroll are mounted independentl of each other above a base which may bexed or adjustable as desired.

It is an object of this invention to provide a Fourdrinier. section of apaper making machine, said section having the various mechanisms to beshaken supportedon wooden spring members affording a construction ofreduced weight and cost, and one in which the Fourdrinier wire may bereadily changed without excessive loss of time or excessive cost oflabor.

It is also an object of the invention to provide a Fourdrinier sectionwherein the table roll rails and the breast roll are independentlysupported on different members and are adapted to be shaken eithersimultaneously or independently.

It is a further object of the invention to provide a-Fourdrinier sectionwherein the breast roll and the table roll rails are supported onseparate light weight resilient members and in which the breast roll,the table rolls and the deckle supports are adapted to be easily removedto permitthe Fourdrinier wire to be readily changed.

It is furthermore an object of the invention to provide a Fourdriniersection wherein the breast roll and'table rails are independentlyconnected to a shaker mechanism so that the breast roll connections withthe shaker mech- 40 anism may be removed if desired and a shak impartedto the table rails only.

It is an important object of this invention to provide a paper makingmachine with a Fourdrinier section of a frameless type and wherein themechanisms to be shaken are supported only by resilient members mountedon a supporting base which may be fixed or pivoted and provided withmeans for adjusting the same. 7

As shown on the drawings:

The reference numeral 1 indicates base I-beams which form a base sectionfor the Fourdrinier end of a paper making machine. Upright members 2 aremounted at one end of the beams 1 and are pivoted at 2" on fixedsupports 2 to permit the opposite'end of said base beams to be adjustedby screw-jacks 54 or any other suitable raising and lowering mechanismsdesired. Mounted upon one end of the base section is a head or flow box3 provided with an apron board 4. Secured to the sides of the flow box 3are bracket plates 5 to which are removably bolted or otherwise securedthe ends of wooden strips or springs 6. The wooden springs 6 are alsoremovably bolted to breast roll supporting brackets Z on which thebreast roll bearings 8 are supported. The'brackets 7 are also supportedby pairs of upright wooden strlps or springs 9 the lower ends of whichare removably secured by bolts to metal brackets 10 fastened to the basemembers 1. Journalled in the bearings 8 are the journals of a breastroll 11'.

Formed on the front breast roll supporting bracket 7 is a side bracket12 to which a U-shaped arm 13 is bolted. Removably connected to oppositesides of the front breast roll bearing 8 are the inner endsof a pair ofwooden strips or springs 14 the outer ends of which are removablyconnected to projecting lugs or arms '16 formed on opposite sides of ayoke 17 which is slidably engaged on a shaker arm or lever 18. The yoke17 is held in osition on the shaker lever 18 by means 0 the yoke arms13. A handle nut 19 and bolt 20 are provided to permit the yoke 17 to beremoved from the lever 18. The arms 13 slidably project between theprojecting lugs 16 and ins or projections 15 formed on the sides of theyoke 17. The breast roll shaker lever 18 is provided with a splitbearing 21 at its lower end which is clamped onto a shaker shaft 22positioned longitudinally along the rear side of the machine.

Secured to the floor in rear of the shaker shaft 22 are a plurality ofspaced pedestals or supports 23 each having secured to the top thereof awooden strip or spring 24. An upright wooden strip or spring 25 is alsosecured to each pedestal 23. The springs 24 and 25 are removably securedto the split bearings 26 of a plurality of shaker arms or levers 27which are secured on the shaker shaft 22 and support the same inposition with the aid of the springs 24 and 25. The springs 24 and 25 onthe pedestal nearest the flow box end are removably secured to the leverbearings 21. The mounting for the shaker shaft 22 isclaimed in mycopending application, Serial Number 5,696, filed January 30, 1925,which in so far as its subject matter is disclosed herein is a divisionof the present application.

Movablv engaged on eaeh'of the shaker levers 27 is a yoke 28. Bolts 29and handle nuts 30 are provided to permit the yokes 28 to be removedfrom the levers 27. Guide pins or projections 31 are formed on the sidesof each yoke 28. Engaged on the shaker shaft 22 is a lever or arm 32 theouter end of which is connected to a link 33. The link 33 iseccentrically connected to a disk rotated by the shaft 35. The shaft isoperated by means of gears 36 driven by a motor37.

Secured at intervals upon each base beam 1 are upright supports orpedestals 38 on the tops of which are secured extension arms 39. Thearms 39 on the rear side of the machine are provided with openings 40(Figure 5). Deekle bars 41 are supported upon the tops of the arms 39 oneach side of the machine and support the deckle rails 42. Deckle straps43 are trained around deckle pulleys 44 and are supported at intervalsby suitable wheels or pulleys 45.

Also mounted upon each pedestal 38 to the inside of the arm 39 areupright wooden springs 46. Bolted to the tops of the springs 46 are thetable roll rails 47. Mounted on the rails 47 are a plurality of tableroll bearings 48 each of which is provided with an adjusting mechanism49. Table rolls 50 are supported in the bearings 48 beneath the decklestraps 43. The Fourdrinier wire has been omitted for the sake ofclearness.

Secured to the rear table roll rail are a lurality of forked guidemembers 51 the orked ends of which slidably project between the guidepins 31 on the sides of the yokes 28 and support said okes on the levers27. Removably connectec to the inner ends of the guide members 51 arethe inner ends of wooden. shaker strips or springs 52. The outer ends ofthe shaker springs 52'ar'e removably connected to the okes 28. Woodensprings 53 are supporte on the front arms 39 with the upper ends of saidsprings 53 supporting the outer end portions of the guide members 51.

Figure 6 is a fragmentary rear side elevation of a modified form of oneend of a Fourdrinier sect-ion wherein the parts are supported upon afixed base 55 instead of on a pivoted base as illustrated in Figure 2.

The operation is as follows: i

It will be noted that a Fourdrinier section of a paper making machinehas been illustrated and described in which the ordinary expensive andcumbersome supporting frame for the breast roll and table rails isomitted and replaced by spring supports thereby affording asubstantially frameless type of Fourdrinier section.

The shaker mechanisms are operated from the motor 37 which rotates themeshing gzea rs 36,-the shaft 35 and the disk 34. Rotation oi the disk34 actuates the eccentric link 33 thereby causing the lever 32 to swingupwardly and downwardly to reciprocate the shaker shaft 22. The shakerarms 18 and 27 are thereby rocked toward and away from the table railsand by means of the members 52 cause shaking of the table rails 47 andthe table rolls supported thereon. The shaker arm 18 actuates themembers 14 thereby causing a shaking motion to be imparted to the breastroll and the Fourdrinier' wire. The upright wooden spring members 9 andthe spring members 6 resiliently support the p breast roll and permitthe shaking motion to be transmitted thereto. If desired the connectingmembers 14 may be removed so that a shake will. not be transmitted tothe breast roll but only to the table rails.

The spring n' embers 24 and 25 connect ed to the pedestals 23 serve asresilient supports for the shaker shaft 22. As illustrated in (hedrawings the resilient wooden spring members 46 support the table railsand permit the same to be shaken by the shaker apparatus hereinbeforedescribed. j

The deckle mechanisms are supported u pm the deckle bars 41 and are notsubjected to the shaking action. The deckle rails may be readlllf)l'il - which the breast roll, the table rolls and the deckle supportsare adapted to be readily removed thereby permitting the 1*ourdrinierwire to be rapidly replaced when necessary. The spring supportingmembers are so arranged that access may be readily had to all parts ofthe Fourdrinier section which was not possible in the old heavy frametype of Fourdrinier constructions.

The base members may be adjusted by means of the screw-jacks 54 aboutthe pivot members 2" to give the necessary pitch to the wire of theFourdrinier section.

While the supports 6, 9, 24, 25, 46 and 53 are described as woodenmembers it will of course be understood that they may be made of anyother desired materials.

I am aware that numerous details of construction may be varied through awide range without departing from the principles of this invention,and'I therefore do not purposelimiting the patent granted, otherwisethan necessitated by the prior art.

Certain of the subject matter of this application is disclosed andbroadly claimed in copending applications of mine, Serial No. 595,- 258filed October 18, 1902; No. 648.959. No. 648,960, No. 648,961 and No.948,962 filed July 2, 1923, respectively and hence is not so claimed inthis application.
